HEATING-DRUM,

SPECIFICATION forming part of Letters Patent No.385,499, dated July 3,1888.

Application filed July 30, 1887. Serial No. 245,673. (No model.)

To all whom it may concern.-

Be it known that I, \VILLIAM MoK. BURNS, a citizen of the United States,residing at Miltouvale, in the'county of Cloud and State of Kansas, haveinvented certain new and useful Improvements in Heating-Drums; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to heatingdrums in which hot-air tubes are soplaced as to present the greatest surface to the heat, and providing forthe admission of fresh air to said tubes and through the same into theroom to be heated.

The objects of my improvements are to so construct a heating-drum asthat it shall readily diffuse heat, greatly economize fuel, and bereadily convertible for use either on top or alongside of a stove or asa separate heater, by being placed in the room above and connected withthe stove below. I attain these objects by the mechanism illustrated inthe accompanying drawings, in which Figure 1 is a top plan of myinvention; Fig. 2, a vertical section through Fig. 1 when used as aheater; Fig. 3, a vertical section showing construction when used as adrum on top of a stove, and Fig. 4 a top plan of the cover to be placedon top of the stove.

Similar letters refer to similar parts throughout the several views.

The drum A has cap B, bottom I, internal heating-tubes, Z Z and E, hole0, with cover a, flue y, with divisions w and x, and damper o. Said cap13 has flanged holes 0 e and K, the hole K being closed by a lid, at,when the device isused on a stove. The circumference of said drum A isextended below the bottom I and forms an air-chamber, which has openingsf f and 2', through which the outside air is admitted to said chamberand thence to said tubes Z Z and E.

If it be desired to introduce the fresh air from without the house, oneend of the airtube a is inserted at the openingz' and the other endextended to the locality from which the fresh air is to be taken. Itwill be noticed that the openingt' is a slot extending to and throughthe lower extremity of the drum A, and shaped at the top to [it theair-tube a, thus allowing the drum to be freely removed from or returnedto its place without disturbing said tube a.

Vhen used as a heater and not resting on the stove, the cover a isremoved and the smoke-pipe H from the stove is attached to the drum A at0, so the smoke and heat enter said drum through the hole 0 andcirculate freely about said hot-air tubes Z Z and E, thus heating theair as it passes through said tubes. Thefluey,which connects with asmokepipe and thence with the chimney through the division x,extends tothe bottom of said drum A, and an opening being made in one side of saidflue at its lower end a draft is created, which draws the smoke from 0through said drum and discharges it through said flue y. By turning thedamper V,which is in the drawings represented as a half-circle pivotedto the casting between the divisions to and w, the division as is closedand the division w is opened, thus allowing a more direct draft acrosssaid drum,as might be found convenient or deemed necessary when firststarting a fire.

For use on top ofa stove, the cover J, having smoke-hole h, is made tofit closely over the top of the stove. A rim, c, on said cover J servesas a flange over or within which to place the drum A, and which may beof sufficient width to close the openingsff, and having an invertedslot, t, to close around said cold-air pipe a, as heretofore describedwith reference to the drum. The covera is placed over 0 and the lid mover It, and the hot-air tube E is converted into the smoke-pipe F bybeing shoved down over the smoke-hole 71, thus leaving an opening abovefor the smoke and heat to enter the drum A, where they cir culate andpass out, as heretofore described.

For convenience of construction and putting together, the cap 13, bottomI, and cover J are cast and have flanges to which to attach said tubes,pipes, and flue; but I do not wish to be confined to this mode ofconstruction, because the whole device may be made of sheet-iron orother metal and without any or all of said flanges.

Having thus described my inventiomwhatll claim as new, and desire tosecure by Letters Patent, is

1. A heatir1g-drnm having the cap B, the bot-tom I, inlets below thebottom, and the openings 0 7c, in combination with the cap a, the lid m,and a suitable smokeflue, as set forth.

2. The eombination,with the heating-drum having internal vertical tubesand an air-chamber below the same, of the central verticallysliding pipeor tube F and the smoke-flue 1 arranged at one side and having anopening at its lower end for the ad mission of the smoke, as set forth.

3. The combination, with theheating-drum having the series of internalvertical heatingtubes, and an air-supply chamber below the same, of thesmoke-flue y,arranged at one side of the drum, and having an opening atits lower end for the admission of the smoke, and provided at its upperend with the divisions w 00, and the damper v, pivoted between saiddivisions, and adapted to close either of them, substantially asdescribed.

4. The combination, with a heating-drum, of the cover J, having rim 0and smoke-hole h, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM MoK. BURNS.
